The frames of theeasement4 win- Adows constitute hollow bars 26 which are somewhatL-shaped in cross section and which have webs 21 on their inner facesagainst which the window panes 28 are secured. The bars 26 also areformed with recesses` 29, and metal clips 3i) are employed to hold thewindow panes against the webs 21, and the recesses 29 affordaccommodation for one end of each clip. The clips, as illustratedclearly in several figures of the drawings, are bowed between their endsand then curved reversely at their ends, one end'of each clip being inthe recess 29 and the other end of the clip bearing against the windowpane, and these clips are covered and enclosed by putty, or othercomposition, 30, so as to hide the same, but the clips strengthen theconnection and hold the window panes against pressure.

The stationary and hinged window panes are `provided with muntins 3| and32. These muntins where they cross* are coupled. Each muntin has a mainweb 33l with relatively wide flanges 34 at one end and relatively narrowanges 35 adjacent their other edge. Where the muntins cross, one muntinis cut out or recessed about threefourths of its width, as shown at 36,which recess extends through the wider flanges 34, and the other muntinis recessed about one-fourth its Width as at 36' to couple to the firstmentioned muntin, so that they may be interlocked, as clearly indicatedin Figure 4 of the drawings. The main flange 34 of the cross muntins iscut away to accommodate the other flange 34 of the cross muntins, and areinforcing plate 3| is secured across the joint and to the muntinseither by riveting or welding, as desired. The narrow flanges 35 serveas abutments for the window securing clips 30, as shown in Figure 3 ofthe drawings.

The main frame A is, of course, provided with a suitable abutment web 31against which the Casement window engages when in closed lposition, andbetween this abutment web 31 and the bars of the-frame throughout an airchamber is formed which also constitutesa condensation chamber with aweep-hole I9 in the lower bar 31 to allow water to drain to the outside.The lower bar of each easement window has a downwardly curved dripiiange 38 to direct water which runs down the window over the juncturebetween the window frame and the abutment flange.

The muntins above referred to where they engage the window frame arecoupled to the frame at their ends by securing elements 39 of doubledove-tailed formation in cross section, located in dove-tailed grooves40 and 4I, respectively, in the frame and muntins, the elements 39 beingdisposed laterally with respect to the muntins. The muntins are furthersecured in the frame by having the main flanged portion 34 cut away fromthe main web 33 at the ends of the muntins and plates 34' welded theretoand to the frame, as indicated in Figures 5 and 6 of the drawings. Bythus cutting the ends of the muntins and providing the plates 34', asindicated,

the webs 42 are securely clamped and the muntins are securely held bythis means as well as by the elements 39.

While we have illustrated what we believe to be the preferred embodimentof our invention, it is to 'be distinctly understood that various slightchanges may be made with regard to the form and arrangement of partswithout departing from our invention, and hence we do not limitourselves to the precise details set forth but consider ourselves atliberty to make such changes and alterations as fairly fall within thespirit and scope of the claims.

What we claim is:

1. A window construction embodying a frame, crossed muntins located inthe frame, said muntins having recesses therein, the recess of onemuntin being appreciably longer and deeper than the recess inthe other,and the recessed portions of the muntins coupled together, said muntinshaving flanges at their edges, the flanges of one crossed muntin beingcut away, a strengthening Atogether with the muntins engaging portionsof the window frame to secure the ends of the muntins to the frame.

2. In a window construction, a frame, muntins, said frame and muntinshaving dovetailed grooves therein, the grooves in the frame beingdisposed directly opposite those in the muntins respectively, thusproviding pairs of grooves, and securing elements each being of doubledovetailed formation in cross section, there being one of said securingelements engaged in each pair of grooves and said elements beingdisposed laterally with respect to said muntins.

3. In a window construction, hollow frame bars constructed of relativelylight metal, each bar having such cross sectional shape as to providerelatively angularly disposed walls, a strengthening bar located in eachof said frame bars and of such shape in cross section as to lie incontact with said walls, and a cap articulated with two of said walls tocombine with all of said walls to enclose said bar.

4. In a window construction, a. easement frame including divisional barsjoined to provide a recess between them throughout the length thereof, astrengthening bar inserted in and lling said recess and projecting fromsaid recess, and a separate cap covering the projecting portion of saidstrengthening bar, said cap and divisional bars being articulated.

5. In a window construction, a easement frame including divisional barsjoined to provide a recess between them throughout the length thereof astrengthening bar inserted in and filling said recess and projectingfrom said recess, and a separate cap covering the projecting portion ofsaid strengthening bar, said divisional bars having longitudinal groovestherein, and said cap having flanges on the longitudinal edges thereofengaged in said grooves respectively, to secure the cap in place.
